3W DC-DC High Voltage Power Supplies

Spellman’s MS Modules have been designed for printed circuit board mounting with high reliability, small size and light weight. Each module provides 3W of output power to 3kV with well regulated low ripple, high stability and high voltage in a versatile, compact cost-effective design. The modules incorporate remote control and arc & short-circuit protection. Radiated pickup is eliminated by sealing each module in an aluminum enclosure.

Typical applications:

Photomultiplier Tubes

Precision Lenses

Image Intensifiers

Nuclear Instruments

Spectroscopy
